And there are two bits of software installed with the Ceton drivers:
1- Ceton InfiniTV Tuning Adapter service. This can safely be disabled or uninstalled if you do not need tuning adatpers.
2- Ceton InfiniTV Diagnostic. I did not include a mention of the Ceton InfiniTV Diagnostic in Part 1 as the final version was not available yet.
Neither software or related drivers require 4GB of RAM. The requirement is part of the DCA.
